Backup Page Freshness Preview Step 1 Solution Assessment

Problem Statement

Users need the backup page to show backup freshness and recent included items before download. Source: thread-20260826031531-923617e0, submitted 2026-08-26T03:15:31Z.

Option A: Show generated-at metadata only

Pros:

• Smallest reassurance improvement.

• Easy to compare against artifact metadata.

• Low UI complexity.

Cons:

• Does not prove what content is included.

• Less useful when users suspect stale cache.

Option B: Show generated-at metadata plus a recent-items preview

Pros:

• Directly addresses freshness and contents.

• Helps users verify the archive before download.

• Can reuse existing activity or read-model summaries.

Cons:

• Needs clear rules for which items appear.

• Preview itself must avoid stale-cache confusion.

Option C: Generate backups only on demand with progress feedback

Pros:

• Strong freshness guarantee.

• Clear user expectation.

Cons:

• More expensive and abuse-prone.

• Slower than serving cached archives.

Recommendation

Recommend Option B.

Brief justification:

• A timestamp plus recent-items preview answers the user's trust concern while keeping the existing backup model intact.
